[ptxdist] [PATCH v2 0/3] cryptodev

[Ladislav Michl]

Hi there!

This serie adds support for cryptodev hardware acceleration.
However, there's one issue unresolved: cryptodev module
loading.
As we have three different modutils implementations available
and also supporting systemd and sysv init it is a bit messy
to generate proper config to load cryptodev at boot time.
So we could either leave module loading to BSP or do something
on ptxdist level. Thoughts?

Thank you,
        ladis

Changes:
- v2: Update cryptodev module to 1.10
      As openssl was updated to 1.1, cryptodev support works
      out of the box now.

This serie was first sent two years ago. Those two years showed
nothing dramatic happened and code still works and compiles.

Btw, I found patch first adding cryptodev in 2010, so perhaps we
want to wait for 10th anniversary? ;-)

[ptxdist] [PATCH v2 1/3] cryptodev: new package

[Ladislav Michl]

Cryptodev-linux is a device that allows access to Linux kernel
cryptographic drivers; thus allowing of userspace applications
to take advantage of hardware accelerators. Cryptodev-linux is
implemented as a standalone module that requires no dependencies
other than a stock linux kernel. Its API is compatible with
OpenBSD's cryptodev userspace API (/dev/crypto).

One more question. Header required by openssl and gnutls is copied
during targetinstall stage. Shall we do it manually inside install stage
to satisfy dependencies?

Subject: [PATCH v3 1/3] cryptodev: new package

Cryptodev-linux is a device that allows access to Linux kernel
cryptographic drivers; thus allowing of userspace applications
to take advantage of hardware accelerators. Cryptodev-linux is
implemented as a standalone module that requires no dependencies
other than a stock linux kernel. Its API is compatible with
OpenBSD's cryptodev userspace API (/dev/crypto).
